제목 Preparation of Titanium Dioxide Nanoparticles Highly Dispersible in Polymeric Materials
초록 Polymer/inorganic nanocomposites have been extensively studied last decade. They usually contain special properties of nanofillers leading to materials with improved properties. Among the various inorganic materials, titanium dioxide (TiO2) can be widely applied to the polymeric materials for the addition of the eco-friendly characteristics. However, the low dispersity of TiO2 due to the agglomeration inevitably results in the degradation of the catalytic activity of TiO2. In this study, we prepared TiO2 nanoparticles highly dispersible in common polymers. Solvothermal method is applied to the preparation, and the nanoparticles show controlled sizes, shapes, and crystalline phases with the precursor concentrations and the types of organic acid. The nanoparticles are incorporated in the polymer matrix through the methods of solution casting and melt mixing, and predominant dispersion of the nanoparticles are observed by transmission electron microscopy.
